A Certified Aircraft Appraisal begins with a thorough on-site examination of the exterior and interior of the aircraft. Special attention is focused on the airframe, paint, engines, propellers, and the condition of instrumentation. The avionics and related flight instruments are inventoried to ensure they are properly accounted for in assessing the value of the aircraft.

The Uniform Standards of Professional Appraisal Practice (USPAP) was established to promote and maintain a high level of public trust by establishing requirements for aircraft appraisers. The Appraisal Standards Board (ASB) of the Appraisal Foundation develops, publishes, interprets, and amends the USPAP on behalf of appraisers and users of appraisal services.
OakTree Aviation Services provides aircraft appraisal services with local inspection capability and nationwide coverage, supporting assignments where the lender, attorney, or fiduciary may be located outside the region of the subject aircraft. Our appraisal reports are prepared in compliance with USPAP and structured for professional reliance.
We routinely perform on-site aircraft inspections throughout Southern California and across California, while serving clients nationwide.
